You don't think that's your decision to make.

"Round two?" You say, your voice shaky. You don't know if you can handle any more of this. Your whole body still feels weak from the orgasm you just had. Stacey leans back and shows you her arm. "Strength of Ten Men" is written on her inner forearm. "Just in case you were wondering how I lifted you so easily." You hadn't, but that did make more sense. "Isn't that overkill?" You asked, suddenly embarrassed. "Do you think I'm fat?" Stacey's expression changed. "What? No, of course not." She leaned down and gave you a kiss on the nose. "You are my scrumptious little button, and I love your size, no matter if that weight is in your muscular back or big boobs." She tweaked your nipple, making you squeak.

Shifting back so she was seated alongside your prone form, Stacey began to write on herself. You couldn't see what she was writing, but you could see the effects. Stacey grew in size, growing taller till she was the height of your male body, then exceeding that. Her muscles bulged, her toned form shifting to that of a sculpted goddess. Her hips and shoulders widened and her breasts expanded to the size of melons. Stacey lifted her eyes up and glanced at you, noting your shocked expression. Then, grasping the marker, she made one final note. Stacey threw her head back as the change overtook her, moaning sensuously. As she did, you caught a glimpse of her bare pussy and erect clit. Then, before your eyes, her clitoris grew, extending out. It grew longer and longer, changing shape as it did. Suddenly, it was no longer a clitoris, but a long, bulb-headed cock.

Ordinarily, you wouldn't know how to feel about this. But your new body did, and it betrayed you. You groaned at the sight of Stacey's flaccid cock slapping onto the bedspread. Stacey rapidly stiffened at the sound, her cock lifting off the bed as it thickened. The slit at the end started to leak pre-cum as the head changed to a reddish color. Between your legs, your new pussy is gushing at the prospect of being pierced by that. You pull your legs together, grabbing your thighs and trying to resist the urge to finger yourself. Stacey stalks over to you on her hands and knees, cock shifting beneath her, pointing down towards your stomach. "Are you ready"

You shake your head. "Stacey, this is-" Stacey is now over you, her body half a foot away, her cock inches above your stomach. She pushes your legs apart and crawls over you, like you're the girl in a romantic comedy and she accidentally fell onto you. In this situation, you actually are the girl, you suddenly realize. You don't laugh though- too distracted by the scene before you. Stacey leans down and kisses you, full on the lips. You feel your heart start to thunder at the taste of her soft lips. It must be this body, but you feel yourself growing wetter, the heat from earlier roaring back up. Stacey's hand slips down and teases your pussy lips, sending jolts of pleasure through you. "It's okay," Stacey coos. "I made it so losing your virginity won't hurt. You'll be fine, I promise." You shake your head. "But I'm a man," she leans down and kisses your neck. You make a soft, feminine noise. "So?" She replies. "You can go back to being a man after this. But surely, aren't you at least the littlest bit curious? Don't you want to know how I feel when you stuff me with your fat, throbbing cock." In between each word, she plants a kiss on your neck and then slowly begins working her way down your chest, teasing the area around your breasts, but never on them directly. You find your hands clenched into fists. You don't know what to do. It's so weird, but it feels so good!

Finally, you nod. Stacey looks you right in the eye and smiles. Then she shifts backwards on the bed again, so she's in a kneeling position, resting on her bare shins. With the grace of a ballerina and the precision of a trauma surgeon, she moves her cock forward and spreads your pussy lips. You flinch, anticipating pain, but you feel none. Instead a wave of pressure and delicious friction run up your spine, making you shudder. "Aaaah!" You cry. Stacey's smug smile vanishes into tense concentration. "Oh wow, Finn. You're so tight." She scrabbles for the marker and scribbles something on her arm. After a second, her expression relaxes slightly. "I was about to pop." She slowly begins to slide out of you. You almost go to complain, before she goes back in. You gasp, the hollow inside your body you didn't know you had suddenly full of her.

Blazing heat spreads throughout your body as she begins to thrust in and out of her. You whine, thrusting your hips up as she pushes in, trying to match her rhythm. It feels so good! Every time she slaps into you, not only is there this wonderful fullness, but she slaps your clit, sending pleasing aftershocks down to your toes. You're moaning now, loudly. "Harder," You beg. "More." Stacey acquiesces, her tempo increasing. She is pounding your pussy and you are loving it.

"I still owe you, Finn," she grunts in between breathes. A small part of your mind wonders what she means, the rest of it occupied with the feeling of Stacey making you her woman. You would laugh, were you not too busy moaning. The fire inside you is heating your entire body. Your pussy is producing enough wetness to quench the fire it seems, but Stacey's cock, it's the plug trapping it inside, pressurizing you. You feel the pressure growing. You're getting close. Just a bit more. You buck your body a bit, your erect nipples shifting as your breasts bounce. They need attention, but your arms are busy holding you up, helping you mimic Stacey's increasingly frantic thrusts. Stacey gets the hint though.

Her strong hands descend and grab your breasts, fondling them. Pleasure explodes through your chest, taking you to the edge. She kneads your breasts like dough, throwing kindling on the fire. Then, in a moment of inspiration, she grabs your nipples and pinches them. And like a single crack in an otherwise flawless design, that's all it takes. You pass the edge and soar off it, plunging into the ocean. Warm waters flood your pussy and drown your in warm waters of pure animal heat. You scream and beg incoherently, clamping down on Stacey's cock. Stacey just holds you, pressing you to her voluminous breasts, your face slipping in between them, while the rest of you is pulled close to her new body, which is hard and hot, but somehow no less lush than before. You ride through your orgasm, the rogue wave that swamped you eventually passing you by, leaving you trapped under your now statuesque girlfriend, her hard cock still stuffed inside you.

"Stacey?" You mutter weakly. She leans down and kisses you on the neck. "Not yet, Finn. I owed you another orgasm." You try to move, but she's trapped you there. "Well, I just had another. So I think we're even." Stacey gives you another kiss on the neck. This time, however, its harder. She licks it, sending shivers through you. "I agree." Then she shifts, getting up and pulling you with her. "This one is for me."

Stacey then spins you around, pulling you up into the air. She moves you, the enormous strength of her new body letting her manipulate you like a doll. She shifts your legs up, till they are almost aligned with your head, then hooks her arms under it. Your pussy is now hanging out, with nothing to protect it, the cool air making you wetness evident as it glistens, your clit and nipples growing hard at the sudden change of temperature. Then Stacey's huge, dripping cock emerges from behind your butt, rising up in front of your drooling slit, pre dripping down it. Stacey turns and suddenly you're lined up with the bathroom, so you can see yourself in the mirror. You realize what she's going to do. "Sta-" is as far as you get.

Stacey lowers you down and thrusts upward. Your pussy is sopping wet and accommodating. It welcomes the recent guest back. You are impaled on her cock, and this time you can watch as she begins to thrust in and out of you. This time, there's no nipple play or soft touches to your clit. She's just ramming in and out of you, using your pussy like a cock sleeve. You moan, your entire pussy clenching. The delicious pressure is heating your pussy again. "Stacey!" You cry. "You're gonna break me!" You're still sensitive from your recent orgasm, each thrust sending pulses of white-hot pleasure into you. You're drooling, flashes of white-hot pleasure making it hard to focus on anything. She's not listening, you realize. She's just using you to get herself off. And yet, you can't help yourself. You love it.

Suddenly, beneath you, you feel her cock throb, sending a pleasing jolt up into you. Then she starts to thrust even harder. You realize what's about to happen. You're transfixed by the mirror, watching her thrust in and out. For a second, you see her face, drawn back, eyes almost rolling back into your head as she cums inside you.

Then it hits. A white-hot blast of fire. A bomb goes off inside your pussy. If earlier it was a wave, this is a raging storm. She paints your walls white and as she does, you are swallowed up. You howl, screaming as each spurt strips you of more of your sanity. The pleasure dips and fades, then rises and falls. But it never relents. Stacey groans as her clenching balls empty themselves inside you. Your body goes liquid in her arms. You can't move, can't think. All you can do is feel. And it feels good, better than it ever has. Stacey manages to set you back down on the bed and then lays next to you. You both lay there, saying nothing, still basking in the pleasure of the act. You rub your belly and feel the smoldering warmth within, as Stacey's cum continues flowing out of your gaping pussy lips.
